SENSITIVITY SWITCH OF VERIFACT A MICROPHONE
For special installations that require less microphone sensitivity or where there is background noise, a sensitivity switch is
mounted to the microphone pre-amp (PC Board) and has two positions, N and L:
N represents normal sensitivity (0dB ouput into 1kΩ)
L represents low sensitivity (-6dB output into 1kΩ)
Louroe VERIFACT microphones are always shipped with the sensitivity switch in normal (N) position. Do not change
unless necessary. To change the sensitivity setting, use a small screwdriver and move slide switch from N to L position.
The switch is mounted on the back side of the microphone housing.
INTERFACING ASK-4 KIT #601 WITH A DVR OR PC SOUNDCARD
The APR-1 Audio Base Station of ASK-4 Kit #601 is compatible with all commercial DVR’s and PC
Soundcards that accept line level input. An RCA cable is included with the kit for connecting Audio Out to
Audio In of DVR. If DVR’s audio input is a 3.5mm jack, an RCA to 3.5mm adapter (not supplied) must be
attached to the plug that connects to DVR’s Audio Input. Check with DVR’s specifications to determine if the
audio input requires a stereo or mono 3.5mm plug.
PC soundcards contain a standard 3.5mm stereo Audio Input or Line Input. Do not use Mic Input of
soundcard. Louroe microphones are line level (0dB@600Ω) and will overdrive the Mic Input. Use “Audio
Input” or Line Input” of the soundcard.

WIRING CONNECTIONS AND TEST
1. Starting with the microphone, using recommended cable, connect RED wire to Pin A, BLACK wire to Pin B and BARE
wire to Pin C. Connect the other end of this cable to MS-1. Connect RED wire from microphone terminal A to
terminal B of the MS-1. Connect bare wire from terminal C of microphone to terminal C of MS-1. Refer to drawing on
page 4.
2. Using another similar cable, connect the APR-1 Base Station to the MS-1. Connect RED wire from terminal A of MS-1
to terminal A of APR-1 base station. Connect the BARE wire from Terminal C of the MS-1 to terminal C of the base
station. Connect the BLACK wire from the terminal B of the base station directly to terminal B of microphone or splice
the cable at the MS-1 using wire nut as shown in the diagram.
4. Plug AD-1 power supply (AC Adapter) into the Power Jack[10] located on back panel of APR-1 first. Then connect 2-
prong block into standard 110/120 AC wall receptacle or power strip.
5. Turn “ON” power to APR-1 by rotating the Power-Volume Knob[1] clockwise. The green PWR[2] LED will illuminate.
Adjust volume of audio by rotating the knob either clockwise to increase or counterclockwise to decrease. Locate
microphone so as not to create feedback with the APR-1. The further the microphone is from the APR-1 the less
feedback it generates. System works best if there is an acoustical barrier between the microphone and the
APR-1, such as a wall or room divider. If there is no wall or barrier, microphone should be mounted at least 25 ft.
from the APR-1 Base Station.
6. Listen to the audio at the base station by turning ON the rocker switch of the MS-1. Audio should be heard at the
base station. Turn OFF the rocker switch of the MS-1. No audio should be heard at the base station.
